"Electronic properties of graphene and graphitic bilayers"


Abstract

Electrons in graphitic monolayers (graphene) and bilayers have very 
unusual properties:  these are chiral quasiparticles which are 
characterized by the Berry phase Pi (in graphene)  and 2Pi (in a 
bilayer). The chirality of quasiparticles manifests itself in a 
peculiar Landau level spectrum and in the form of the quantum Hall 
effect. It also generates specific quantum transport characteristics, 
such as selective transmission and magneto-resistance in ballistic n-p 
junctions in graphene, and it gives rise to a rich variety of weak 
localisation regimes in a monolayer and a bilayer.
